TANK-HEATER.

Specification of Letters Patent. Patented Sept, 19, 1916,

Application filed March 22, 1815. Serial No. 16,272.

To all whom it may concern Be it known that I, LEWIS C. HADsALL, acitizen of the United States, residing in the county of Jasper, State ofIowa, have invented certain new and useful Improvements inTank-IIeaters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to tank heaters and particularly to devices ofthis character adapted to heat the water in stock tanks to prevent samefrom freezing in extremely cold water.

The object of the invention resides in the provision of a device of thecharacter which will be simple in construction, eflicient in use andwhich can be manufactured at a comparatively small cost.

Vith the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended clain In describing the invention in detail reference willbe had to the accompanying drawings wherein like characters of referencedenote corresponding parts in the several views, and in which- Figure 1is a view in elevation of a tank heater constructed in accordance withthe invention; Fig. 2, a plan view of same; Fig. 3, a section on theline 33 of Fig. 2, Fig. 4, a section on the line 4-4 of Fig. 1; Fig. 5,a perspective view of a fragment of the furnace looking at the innerside thereof.

Referring to the drawings the invention is shown as comprising a tank A,a furnace B and a smoke box C. The tank A includes side members 10 and11, a bottom 12 and end members 13 and 14. The side and bottom membersof the tank are extended beyond the end members to form flanges 15 and16 respectively. Extending longitudinally with the tank and having theirterminals mounted in the end members 13 and 14 are heat flues 17.

The furnace B is in the form of a casing and includes the usual grate 18and heat escape opening 19 formed in one side thereof above the grate18. The front and rear walls of the furnace B are provided withcorresponding recesses 20 and 21 located just at the bottom of theopening 19. The top wall of the furnace B is provided with a securingflange 22. The front wall of the furnace B has mounted therein afire-box door 23 and an ash pit door 24. The furnace B is connected tothe tank A adjacent the end member 13 by disposing the flange 16 in therecesses 20 and 21 so as to bring the flanges 15 in overlappingrelatiomwith the front and rear walls of the furnace and then passingrivets through the flanges 15 and the front and rear walls of thefurnace. To complete the application of the furnace to the tank theflange 22 is riveted directly to the end member 13.

' The smoke box C is also in the form of a casing having one side open,the flanges 15 and 16 adjacent the end member 14 overlapping the sidesand bottom of the smoke box respectively and being secured to the latterby means of rivets. The top of the smoke box C is provided with anopening 26 surrounded by a flange 27 over which is engaged the lower endof a smoke pipe 28. The closed side of the smoke box C corresponding tothe end member 14 is provided with openings 29 in line with the flue 17whereby the latter may be readily cleaned. The openings 29 are normallyclosed by pivoted doors 30.

What is claimed is:

In a device of the class described, the combination of a tank having itsside and bottom members extending beyond its end members to formsecuring flanges, heat flues extending longitudinally through the tankand having their terminals supported in the end members of the tank, afurnace member having one side provided with an opening and its frontand rear Walls provided with corresponding recesses at the bottom ofsaid opening and receiving the flange at the adjacent end of the bottommember of the tank and whereby the flanges at the ends of the sidemember overlap the front and rear of the furnace, rivets engaged throughthe furnace and the last named flanges, a flange on the top of thefurnace, rivets engaged through said last named flange and the top ofthe adjacent end member of the Walls of the smoke box and the overlyingflanges 0f the tank.

In testimony whereof, I aflix my signature, in the presence of twoWitnesses.
